Deborah Meaden joined the British television show Dragon's Den in series 3.
Meaden became one of the programme's best-known investors after entering the panel during its third series. Before Dragon's Den, she had built a career in business and investment, including work connected with family entertainment and leisure enterprises. Her direct questioning and emphasis on practical commercial details became a recognisable part of the show.
Her arrival followed the programme's initial launch period and helped establish the panel as a changing group rather than a permanently fixed cast. Meaden went on to become one of the longest-serving regular Dragons.
Series numbers can be confused with broadcast years because the programme has not always followed a simple one-series-per-year pattern. The precise answer is series 3, not the year in which viewers may remember a particular investment or special episode.
